Vibration might be lower control arms. The liquid-filled bushings wear out and cause vibration in the 45-60mph range. The E39s are known for this. Just a thought in case the wheels don't fix the problem.

it's not an E39, it's a E30
E30 with E39 wheels to be exact
and i didn't have any issues with the old wheels
so i know its because of the hub adapters
the E39 has 74.1mm hub
E30 has 72.5mm hub

so i need these small hub adapters that fill in the gap
the ones i had from ebay look damn cheap
the ones i got from sonic tunining look much sturdier
well built
just the weather hasn't been cooperating lately for me to put them on
